When enabling HHVM and having a big amount of posts or WooCommerce Products, it causes a 502 Bad Gateway when trying to access the posts/products in wp-admin
What can I do?
Switch to PHP-FPM?
We should probably add a note to Trellis about potential HHVM issues with our setup, but it also might just have bugs itself.
You need to also look into changing values such as max_execution_time
.
